Embodiment Construction
[0025] In following description, the detailed is set for people to understand the present invention, but not to limit the scope of the present invention. The present invention can be implemented without some of the detailed for person who has a common knowledge in the field. The following description is explained as embodiments by referring to the drawings. The present invention is not limited to the embodiments. The modification of the embodiments should be deemed within the scope of the present invention, if the modification is made on basis of the spirit of the present invention.
[0026] The embodiment of pre-segmentation method of the present invention is explained as follows. The flowchart of the pre-segmentation of the present invention is found in FIG. 2. In process 1, by YUV, in sample of 4:2:0, a macro block (16×16) as a target macro block on basis of CCIR601 standard is inputted. The macro block (16×16) is divided into four 8×8 middle square blocks, and further each 8×8 mid...

The present invention relates to a pre-segmentation method for inter-coding and a mode pre-selection method for intra-coding in accordance with standard of advanced video coding. The pre-segmentation method of the present invention is used to pre-segment macro-block for decreasing the times of comparison needed in following inter-coding process in accordance with standard of advanced video coding. The pre-selection method of the present invention is used to pre-select modes from all possible modes so as to reduce the computing complexity in following intra-coding in accordance with standard of advanced video coding.
Description
FIELD OF THE INVENTION [0001] The present invention relates to a pre-segmentation method for inter-coding and a mode pre-selection method for intra-coding in accordance with standard of advanced video coding. In particular, the present invention relates to a pre-segmentation method used to pre-segment macro-block for decreasing the times of comparison needed in following inter-coding process in accordance with standard of advanced video coding, and relates to a pre-selection method used to pre-select modes from all possible modes so as to reduce the computing complexity in following intra-coding in accordance with standard of advanced video coding. [0002] The above pre-processing could simplify the compression complexity in advanced video coding as well as maintain the image quality. PRIOR ART [0003] Recent years, in trend of multimedia and networks, a research in high-speed receiving / transmitting system with high quality video information attracts more attention than ever. Under th...
